In the title dinuclear complex, [Na2(C8H6NO4)2(C8H7NO4)2(H2O)6], which is located on a crystallographic inversion centre, each Na+ cation is coordinated by three carboxylate O atoms from three isophthalate ligands and by three water mol­ecules, displaying a distorted octa­hedral geometry. The separation in the centrosymmetric dinuclear complex is 10.251 (3) Å. Intra- and inter­molecular N—H...O and O—H...O hydrogen bonds and π–π inter­actions (interplanar distance of about 3.43 Å) produce a supra­molecular network.

Comment top

Molecular self-assembly of supramolecular architectures has received much attention during recent decades (Kim et al., 2003; Iglesias et al., 2003; Moulton & Zaworotko, 2001). The structures and properties of such systems depend on the coordination and geometric preferences of both the central metals ions and bridging building blocks as well as the influence of weaker non-covalent interactions, such as hydrogen bonds and π-π stacking interactions.

As illustrated in Fig. 1, in the dinuclear centrosymmetric structure of (I) each NaI centre is coordinated by three carboxyl O atoms from three 5-aminoisophthalato ligands, and three water molecules. In the distorted octahedral geometry each of the water molecules is located trans to a carboxyl O atom (Table 1). The Na···Na separation within the centrosymmetric dinuclear complex is 10.251 (3) Å, and the the two central 5-aminoisophthalato ligands are parallel to each other at a plane to plane distance of about 3.43 Å, thus indicating a π stacking interaction (Fig 1). The structure is further extended to a supramolecular network through intra and intermolecular N—H···O and O—H···O hydrogen bonding interactions (Fig 2., Table 2).

Experimental top

The title complex was prepared by the addition of 5-aminoisophthalic acid to a hot aqueous solution. The pH was then adjusted to 7.0 to 8.0 with NaOH (0.1 mol/L). The resulting solution was filtered, and colourless crystals were obtained at room temperature on slow evaporation of the solvent over several days.

Refinement top

Carbon-bound H atoms were placed at calculated positions and were treated as riding on the parent C atoms with C—H = 0.93 Å, N—H = 0.96 Å and with Uiso(H) = 1.2 Ueq(C) and 1.5 Ueq(N). Water H atoms were tentatively located in difference Fourier maps and were refined with distance restraints of O–H = 0.82 Å and H···H = 1.29 Å, each within a standard deviation of 0.01 Å, and Uiso(H) = 1.5 Ueq(O).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
